The Yellow Perch is a very adept fish at
acquiring food. It eats many different types of food such as
small fish, insects and even zooplankton. Insects such as
mosquitos are even eaten, not just those insects in
the water.

The Perch has two different ways it can eat; either it can
use its teeth to catch fish and insects or it can use its gill rakers to try and
filter out the zooplankton that is in the water.

The Perch does not have much fat on its body, being that it has usually less
than 1%. Not only this, but it also has a closed circulatory system that uses a

counter-current on the gills to obtain
the maximum amount of oxygen. This is perhaps one of the reasons why it is able
to withstand low oxygen enviornments.
